Abstract

The insecticidal and repellent properties of essential oil and powder forms of Schinus molle were evaluated on Tribolium confusum in laboratory conditions. As a result of the studies, it was revealed that the average lifespan of T. confusum was 30±2 days. Egg incubation period was 10 days while the fecundity was 78 eggs/female. Sex ratio was observed as 1.06 female/male. In vitro insecticidal tests showed that the essential oil of S. molle was more effective with a mortality rate of 100% in 24 hours. The adults (males and females) of T. confusum survived for less than 24 hours in powder of S. molle. The repellence test of the essential oil provided variable levels of protection ranging from 78% to 100%.
